The environmental warehouse body 1 is provided with an exhaust valve 7 for exhausting air to the outside, an air supply pipe 8 for supplying air to the inside, and a blower 9 matched with the air supply pipe 8. The fresh air passing through the evaporator 6 is blown into the air supply pipe 8 by the blower 9. The artificial environment warehouse system also includes an energy storage box 10 and a surface cooler 11. The energy storage box 10 is equipped with a coolant. The energy storage box 10 is connected to the heat pump cycle in a heat exchange manner. The heat pump cycle can use solar power supply electricity and / or valley price electricity to store energy in the energy storage box 10.

[0031] The surface cooler 11 is used to utilize the energy in the energy storage box 10 to pre-exchange heat for the fresh air when there is no solar power supply and / or peak-price electricity, and then the fresh air passes through the evaporator 6; the surface cooler 11 is arranged on one side of the evaporator 6, forming a series relationship on the fresh air flow path.

[0032] The environmental bin body 1 is also provided with a return air valve 12 , which is used to mix the internal air of the environmental bin body 1 with fresh air, and then pass the fresh air through the surface cooler 11 .

[0033] The coolant in the energy storage tank 10 can be water or other liquids with high specific heat capacity. The refrigerant inlet of the energy storage tank 10 is connected to the heat pump cycle through a three-way valve 13; the refrigerant outlet of the energy storage tank 10 is connected to the heat pump cycle.

[0034] The energy storage tank 10 is provided with an energy storage heat exchanger, which is a shell and tube type or fin type radiator, and is used for heat exchange between the refrigerant in the heat pump cycle and the secondary coolant in the energy storage tank 10. The first interface of the three-way valve 13 is connected to the refrigerant inlet of the energy storage tank 10, the second interface of the three-way valve 13 is connected to the expansion valve 5, and the third interface of the three-way valve 13 is connected to the evaporator 6;

[0035] The refrigerant outlet of the energy storage tank 10 is connected to the evaporator 6. The coolant outlet of the energy storage tank 10 is provided with a booster pump 14, the outlet of the booster pump 14 is connected to the inlet of the surface cooler 11, and the outlet of the surface cooler 11 is connected to the coolant inlet of the energy storage tank 10, thereby forming a coolant circulation.

[0036] A condensing fan 15 is matched on one side of the condenser 4. The exhaust valve 7 mixes the air exhausted from the environmental bin body 1 with the fresh air outside, passes through the condenser 4, and is then drawn out by the condensing fan 15.

[0037] The air supply pipe 8 is also connected to a humidifier 16; a temperature and humidity sensor is provided in the environmental chamber body 1.

[0038] The principle of the utility model is:

[0039] The heat pump cycle includes components such as compressor 2, four-way valve 3, condenser 4, expansion valve 5, evaporator 6, etc. Through the interaction of these components, the system can achieve energy transfer and conversion. In the evaporator 6, the refrigerant absorbs heat from the external environment and evaporates, thereby reducing the temperature; in the condenser 4, the refrigerant releases heat and condenses, thereby increasing the temperature.

[0040] The energy storage tank 10 is equipped with a coolant, which is connected to the heat pump cycle in a heat exchange manner to achieve energy storage and release. When the solar power supply energy and / or valley price electricity are sufficient, the system stores these energies in the energy storage tank 10. When these energies are insufficient, the coolant in the energy storage tank 10 exchanges heat with the refrigerant in the heat pump cycle through the heat exchanger, releasing energy to maintain the temperature of the environmental warehouse body 1 stable.

[0041] The surface cooler 11 is used to pre-exchange heat for fresh air using the energy in the energy storage tank 10 when there is no solar power supply and / or peak-price power. In this way, the fresh air has been preheated by the surface cooler 11 before entering the environmental warehouse body 1, reducing the energy consumption of the heat pump cycle and improving the energy efficiency of the system.

The humidifier 16 further adjusts the humidity inside the environmental warehouse body 1 to ensure accurate control of temperature and humidity.
